i aeeoinpnnying drawing, forming a part of This type of boiler iisiiiil Be it known that Lili-:aunar sllmiriiuizv, a citizen of the United States, residing atiy i...lamazoo, Michigan, have invented eer-a tain new and usefullmprovemcnts in Waterlleiilers, of which the following is a specification.

This invent-ion relates to improvements in water heaters.

ln water heaters of the automatic type, it is desiriible to employ a boiler which utilizes as Areat a proportion of the heat units of the nel consumed as possible. and thol coil type of boiler is frei uently employed. i

ly has many feet i of copper tubing which is etl'eetive in taking up the heat, but. which also radiates the heat with equal facility, so that a conl siderable amount of fuel is Drequired to merelv compensate. for this rndiiitioii or loss lt is the iuaiii object of iiiy prescnt invcn I lion to provide a wiiter heater in whieh the water in the. delivery or house system is maintained at a suitable temperature, with a minimum consumption of fuel. i

Further objects, aud objects relating to .structural details, will definitely appeal' from tht` detiiiled description to follow.

l accomplish thc objects of in v invention t h v the devices and means described in the following specification. 'lhe structure dei scribed constitutes one effective embodiment of my invention. Other embodiments would be readily devised bv those skilled in the art.

'l'he invention is clearly defined and pointed out iii the claims.

A structure coiistitiitin nii effective and preferred embodiment o the features of my invention is clearly illustrated in the this specification, in which:

l`igure 1 is a detail side elevation of a structure embodying the features of my invention, the delivery system for the heater being conventionally illustrated. Fig. 2 is an enlarged detail section through the valve y mechanism.

In the drawings, siiiiiliir reference characters refer to similar parts throughoutl thc` several views, and the sectional views are taken looking in the direction of the little arrows at the ends of thc section lines.

lteferring to the drawing. the main heater illustrated is of the coil type, the coils2bcing arranged within the heater casing 3, whici is shown as double. wiilled to prevent radiation. 'l`he gas burners 4 are located below .the heatingcoils. The water supply 5 is connected to the uiper ends of the coils through the inlet vn ve casing 6. This inlet valve casing is provided with a cold water inlet. connection 7, and a cold water discharge S, the inlet. being connected to the water supply 5, and the discharge (i to thc upper end of the heater coils by the pipe 9. 'lhe valve casing is iilso provided with a hot. water inlet. 10 and discharge 11, the inlet being connected to the delivery pipe ll of the heater coils, preferably through the thermostat tube 13. The discharge 11 is eonnccted to the draw-ofi` or delivery system 14, which is shown in conventional forni in Fig. 1.

'l`lie hot wiiter inlet l0 is preferably connected willi the. cold water discharge by means of the circulation passage or port l5. The water inlet valve, preferably of the piston type. as shown, consists of an, inner member 1G and an outer member 17, adiipted to seat therein. When the inlet valve is in its open position, it closes o r cuts ott' the connection between the het water inlet l0 and the discharge R, so that the supply water is directed to the heater.

'l`hc gas valve casing 18 is preferably eoniiected to the water valve casing by means of the yoke 19, so that the parts are. held in proper alinciueiit. 'l`he gas valve .20 is held normally on its seat by means of :i springr Q1. 'lhc gas valve, in the embodiment. of my inventiouiillustrated, is opened by the water inlety valve. 'lhe stein 2Q of the gas valve is arranged to be engaged by the stem Q11 of the water valve. '.lhe stem Q3 is carried by the member 17 of the inlet valve, so that in r thc event. of the member 1G becoming clogged or retained in its open position on account of sand or sediment, the member 17 is rctiiiiied to its initial position by means of the gas valve spring 2l, thus permitting the gas valve to close when the drawing of water from the heater is discontinued, even though the member 1G of the inlet valve sluill be retained in its open position.

The inlet valve is normally returned to its closed position, when the drawing of water is discontinued, by means ofthespring 24. The inlet. valve member 16 is preferably provided with circulation ports Q5, which arc normally closed tothe inlet water by the member 17 of the inlet valve. Should, however, the member 1G be retained in its open position, the water is free to circulate, through the iorts 25, not only the wiitcr contained in t ie heater, but. any waterdrawii from the system on the ripening of a drawofl' faucet of the delivery system. The =heater is thus rendered inoperative until provide a transverse groove 2T at the inner end of the valve chamber, and a discharge passage 28 opening into the discharge connection for the heater to the valve casing. The valve, in its operation, has a tendency to wi e any sediment that may collect in the i va ve chamber, either into the water dis-- charge 6 or into the passage Q8. lVhen the water is being drawn from the heater, any 't sediment that may collect in this passage .28 is sucked into the discharge and drawn oil', or it will settle in the thermostat tube, from which it may be drawn oil' by means of the valve 29 at its lower end. I preferably provide, in this connection, a thermostat actuii-ets to be engaged by the lever Zll, which is ,actuated by the thermostat rod 9.5. 'l`he lever Zl. is pivoted :it itil and is acted upon iliv the lever Ill, which is aetmited by the tl'iermostat red t. 'I'he uiaiu advantage of this thermostat actuated valve is to regulate. the temperatureof the water passingthrough the heater. Also, in the event thaty the gas valve IS .should t'ail to close, although the walls. To further this result, I preferablyl :ded gus vulve ltl. the .stein 3l of which pi'n- `possibility of this is reduced to a minimum 1 when used in connection with my improved water inlet valve illustrated, the thermostat, b v the circulation of the water through the =described is that shown in my application for Letters latent tiled January 28th, 1910, lQerinl Number 540,570.

lt is. of course, desirable that the water in the delivery or house system shall be mainiaiiied at a silitable temperature. When the water in the system is permitted to circulate through the heater, as is shown iii my latent` No. 800.057, ot' June tl, i008, a cousiderable iiiiiouiit of fuel is required to coini pensate for the radiation inthe heater tubes, 'as before pointed out. This l obviate by providing an auxiliary heater which`l ai'- range in the delivery system, so that the water is permitted to circiiliite through this auxiliary heater independently of the main lieatei. lly this means, I am enabled to iiiaiitaiii the temperature of the waterin the heater, will promptly close .the valve. 30.-` 'l`his valve mechanism I have illustrated and system at. the desired point, without circiiflating it through the main heater.

In the structure shown, the auxilia lheater consists of the heating coil 3G, wliici i is connected in the system as is diagrampling "t0 having a deflector 4l therein. lt is obyious that a check valve would answer this purpose, but the detlector is preferably iused as there are no parts to become wedged or clogged.

lyhen water is not being drawn from the jdelivery s vstem, the water therein circulates throiigi the system to the auxiliary heater, -and is maintained at the proper tempera ture. lYhen, however, water is drawn from the delivery system, the incoming water must pass through the main heater and this ,wapens the gag valve thereof automatically so St at. the main heater ls in use as long aq water is being drawn from tlu` system, and

is automatically eut. out when the drawing 1 of water is discontinued. l ani thus enabled to have a supply ot hot water for immediate. -use. withoutthe necessity of keeping the niiiiii heater in actionand this results in a considerable saving of fuel.

l have illustrated and deseribed my present improvements largely in diagrammatic. or conventional form, as ilie structural details thereof may be very gi'eatly varied as will be readily understood by those skilled in the art to which this invention relates.
